keyword=No Lumi Data. Missing helicity and target signals to HAPPEX Right Spectrometer crate.
The right spectrometer crate, which reads out the lumi, is missing data
from the target spin and helicity signals. These were plugged into the
input port of the TIR. They may have accidentally been unplugged in some
location during the holiday down.
We (Joe and I) will need an access to investigate/fix this. The lumi
data inserted into the Transversity datastream is meaningless (all zeros)
until this is fixed. Lumi data into the HAPPEX datastream is fine... but
does not contain information on target spin.
Maybe this doesn't matter until we go back to vertical target polarzation?
